BARREL- LINING.

SPECIFICATION forming part of Letters Patent No. 290,721, dated. December 25, 1883.

' Application filed October 29, 1883. (No model.)

To all whom it may concern:

Be it known that I, PHILIP? UYRIoH, a citizen of the United States, and a resident of Minneapolis, in the county of Hennepin, in the State of Minnesota, have invented certain new and useful Improvementsin Barrel-Linings, of which the following specification is a full, clear, and exact description, reference being also had to the accompanying drawings, in which- Figure 1 is a perspective view of a barrel lining arranged therein. Fig. 2 is a perspective view of one of the linings removed from the barrel and rolled up. Figs. 3 and 4 represent the heads of the lining. Fig. 5 is a perspective View of one of the blank linings before being rolled up and placed in the barrel. Fig. 6 is afront elevation, Fig. 7 is a side elevation, and Fig. 8 is a plan view, of a system of convex and concave rollers used in forming the blank linings.

This invention relates to barrels in which flour and similar material is transported; and it consists in a paper lining suitably formed into a curved or dishing shape by pressing, rolling. or by other means, so that when rolled up and inserted into the barrel the lining will closely fit the curved and circular interior of the barrel, as hereinafter shown.

F represents the barrel, and G the paper lining. If the linings are formed from paper already manufactured, sheets of the proper size and form will be pressed between convex and concave metal plates to impart to them the proper dishing form; but when formed direct from the pulp when the paper is being manufactured, I preferably use a series of pairs of convex and concave rollers, A A A B B B, suitably mounted in frames G 0 and revolved by belts and pulleys D or other means. The upper set of rollers will be adjusted by set-screws a, to regulate the press- The pulp is first fed to the first set of rollers A B, which are set some distance apart, and from thence to the second set A B, which are set a little closer together, and from thence to the third or finishing set, which are set as close as the required thickness of the paper. The convex rollers B B B being largest at their centers, and the concave rollers A A A being smallest at their centers, and all being revolved at the same axial speed, the centers of the rolls will travel a little faster than the ends. Consequently the paper will be forced through faster at the center and held back slightly at the ends,whereby the proper curved and dishing form will be given it, as shown in Fig. 5. The rollers will be ofa diameter proportionate to the length of the paper linings required, so that the paper strips or webs leave the rollers formed into dishshaped linings at equal intervals, which may be cut up into proper lengths.

An automatic knife may be attached to the roller-frame to cut the linings off at the proper intervals, if required. By this arrangement each lining fits the interior of the barrel perfectly, requiring only to be held by one or two small tacks at b b, where the ends lap each other.

No paste or other similar material is re quired to hold the linings in place, and even the tacks above mentioned are not always necessary, as a center-punch indentation made through the two parts of the linings where the ends lap will hold them suiiiciently.

Circular heads H H may be used between the heads of the barrel and the contents of the latter, but will not always be required.

Any suitable kind of paper may be used; but I prefer the common heavy straw paper as being the best for the purpose, as it will more certainly prevent the passage of moist ure than any other quality, the preserving of the contents of the barrel from the action of moisture being the principal object of the paper linings.

Having described my invention and set forth its merits, what I claim is- As a new article of manufacture, a barrellining of paper formed in a curved or dishing shape, so that when rolled up and inserted into the barrel it will conform to its curved and circular interior, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
